Smile Spa is a fabulous dental office! First off, I have a dental anxiety. Their kind and friendly staff made me feel comfortable immediately. Not only did they answer all of my questions, but provided even more important and helpful information to assuage my concerns. In addition to the neighborly feeling of the office, their fees were very competitive! I couldn’t be happier or more pleased! I have already recommended the this office to several people. Spread the word! Smile Spa is a very professional dental service–the best I’ve ever experienced!

Elizabeth J. from Irvine, CA (Source: Yelp)


If you’re still thinking about which dentist to go to, I’ll make it easier for you.  This place is absolutely amazing! The staff are very welcoming and they get things done quickly. If you always catch yourself looking at your watch because you’re nervous about making it to your next schedule, no need to do that here. If there were more stars to give, I would. Thank you Dr. Cho for giving me such a great experience!

Susan F. from Laguna Beach, CA (Source: Yelp)


Dr. Cho and his staff at Smile Spa dental are amazing! I’m usually afraid of the dentist but they made me feel so comfortable and it was so clean and nice that I wasn’t worried at all. Rachel and Inga, the hygienist and assistant are so personable and professional, and Jennifer the front desk manager was a doll and very accommodating. I am recommending this place to all my friends. Thank you Smile Spa. I feel like a new woman!

Tony L. from Yorba Linda, CA (Source: Yelp)


A friend introduced me to Dr. Cho and I brought my 7 and 9 year old for a check up. He was extremely thorough and explained to me all the options for my son’s cavity. We decided to get his cavity filled and work was performed right then and there. Very gentle and no crying! First time with no tears at a dentist. I think we finally found our long-term family dentist! Highly recommended!

Joe U. from Northwood, Irvine, CA (Source: Yelp)


I’ve had many bad experiences with dentists, so I was hesitant to come to a new one. My first impression of smile spa was awesome. They say me down in a massage chair to ease my anxiety, and the staff was super welcoming. Dr. Cho explained the procedure he was going to performing in very layman terms and helped me feel at ease with the whole appointment. He was very gentle and meticulous in his work, and I came out completely satisfied with his work. Definitely recommend Dr. Cho and smile spa for anyone needing dental work.

Kim C. from Newport Beach, CA (Source: Yelp)


Dr. Cho and his staff are very nice. Prices are very fair. This surprised me because of location. I was referred by a friend. My dentist was a bit over priced. In fountain valley. Dr. Cho did a root canal. Pryer to this a specialist always did my root canals. During procedure I felt no pain! Dr. Cho is also good at giving numbing shot. When you walk in their lobby there is a coffee and tea bar. Not to mention, refrigerated bottled water and snacks.  In the restroom, disposable toothbrushes (pre-pasted). Last week they had toothpaste samples at check out area. Oh also one can watch net flix while under going procedure. My kind of dental experience for sure..

Maria P. from Culver City, CA (Source: Yelp)


I moved and finally got around to finding a new dentist and Smile Spa made the process incredibly easy. They sent me reminder emails/call to confirm my appointment which is much appreciated. Rachel did my teeth cleaning and she was so great. Incredibly friendly and did a wonderful job. Easy patient parking under the building and the office is nice and clean. Definitely recommend this group!

Lisa K. from Laguna Beach, CA (Source: Yelp)


Great service all the way around.  Besides cleanings, I’ve had two small procedures done here, and Dr. Cho made them a breeze. Hygienist, Rachel, and the other ladies in the office are the best.  What more can I as for?

Ryan M. from Newport Beach, CA (Source: Yelp)


As a new and now current client I was welcomed with such professionalism by the staff of Smile Spa Dental.  After having X-Rays, Rachel provided a great and comfortable deep cleaning.   She was very knowledge and addressed my concerns that I had, also showing me the correct way to brush and floss my teeth.  I would highly recommend Smile Spa to anyone looking for a great dentistry, they mean business.

Jonathan S. from Irvine, CA (Source: Yelp)


Typically I am absolutely terrified when it comes to the dentist. First off there is that smell of anesthesia, and then of course, the pain. As with anything, including food, I want to know what is going into my mouth, and what is going to be done. I would consider myself to be a very fastidious person when it comes down to food and when I’m deciding who is going to be drilling and poking needles into my body. With that being said, now comes my review of Dr. Arnold Cho and his practice known as, “Smile Spa”. The first thing I noticed when I went to him for a filling was the absence of the anesthesia smell that is stereotypical of all the other dental offices I have visited. This was a huge relief to me as it seemed more like an actual spa. It was very nicely decorated, and the staff was very welcoming and accommodating. They seemed to have all the latest technologies associated with their field benignly hidden in a spa like environment. To put me even more at ease, Dr. Cho was very professional and went through the procedure with me making sure that there wouldn’t be any surprises. After the procedure was done, I was amazed at how much he had minimized the pain and how quickly the time had lapsed. Before I knew it, I was out of there. Dr. Cho and his staff have definitely alleviated my fear of the dentist. It has been several years now since I have entrusted him as my dentist, and I have had multiple procedures done by him including fillings, wisdom teeth extractions, and root canals, all of which have been a “better-than-I-had-anticipated” experience. I highly recommend this place!

M. J. from Victorville, CA (Source: Yelp)


The staff over at smile spa has been more than helpful. From our first phone conversation to the several appointments later, they have been wonderful. Their communication has provided me with the upmost understanding of what is planned and how to better my overall hygiene. They have been helpful and more than supportive throughout the whole process. I highly suggest anyone with a ppo option to take advantage of the many services they provide.i will continue to suggest their services in the future!.

Donald D. from Central LA, Los Angeles, CA (Source: Yelp)


I love coming here! i am so glad that i found dr cho! i was researching and i saw all these 5stars reviews.. i gave it a try and i’m so happy that i did. i was always afraid of seeing a dentist but dr cho totally changed my mind 🙂 also staff are very friendly and professional!! thank you gloria and sara!! also dr cho! he’s very down to earth and knowledgeable. very transparent about procedure and i really feel like i’m in good hands. i asked lots of questions but he was very patient with me and made sure that all my questions were answered. office is very nice and clean too. i live in tustin and i am so willing to drive to new port beach. that’s how much i like it 🙂 i recommend this place to everyone! you won’t regret it!! Dr. & Staff : 10/ : 5/5. location : 5/5. parking : 5/5.

Bjorn M. from Artesia, CA (Source: Yelp)


I was reccomended to this place by my sister who works there as a Dental Assistant and I can see why she did! Dr. Cho is all about business and knows how to get the job done quickly and professionally. So far here I have had a cleaning and a root canal and both times I was totally impressed.…using the massage chair after getting work done is a nice addition as well 🙂 This will be my home for getting anything done to my teeth! You should check it out and make it your home too!

Steve S. from Costa Mesa, CA (Source: Yelp)


I needed some extensive dental work and was price shopping dentists in the Newport Beach area, while at the same time looking for a nice, modern facility that offered quality work. I called Dr. Cho’s office to get a quote on a procedure and he was significantly less expensive than several others in the area. When I went to my first appointment I knew I had a good decision! Dr. Cho and his staff were obviously extremely competent and genuinely concerned about giving me the best possible care. I now have my smile intact and I fully intend to continue seeing Dr. Cho for ongoing maintenance. Bottom line: If you need a quality dentist in the Newport Beach area and want to avoid the Newport prices go see Dr. Cho, Jennifer, and Inga; you won’t be disappointed!

Vanessa P. from Newport Beach, CA (Source: Yelp)


My family and I have been coming to Smile Spa for over 5 years now. The office is so beautiful and modern. They have a massage chair and complimentary moisturizing gloves that makes my dental appointment feel like a spa experience! I have referred friends here as well that are now regular patients too. Dr Cho is very thorough, compassionate, and professional. Inga and Jennifer are always so friendly and caring. Every appointment is such a positive experience. I highly recommended Smile Spa if you are looking for a great dentist and staff!

Gloria Y. from Los Angeles, CA (Source: Yelp)


I came to Dr. Cho’s office after I was told by another dentist in Buena Park that the solution to my toothache was a root canal because the tooth was “dead.” Dr. Cho took some x-rays and informed me that the pain in my tooth was caused by inflammation and a root canal was not necessary. It’s difficult to find businesses that don’t take advantage of your money in a field you are not familiar with. But thanks to Dr. Cho & his honesty, I saved a lot of $$$ and I still have that tooth today! (Also, Smile Spa is very clean…  & the interior is nice.. even the bathroom is nice!)

Lillian L. from New York, NY (Source: Yelp)


I totally dread going to the dentist but this dentist makes me feel like I’m truly in a heavenly spa. Snagged that Groupon deal for a free checkup/cleaning, got free parking, was invited to the chair of .. pain no. I was offered spa moisturizing gloves, Netflix -caught up on the last episode of Terrace House (a snobby Japanese soap opera show that I shamefully watch religiously) while the assistant and dentist professionally cleaned my teeth AND did a superb job. Honestly, I didn’t want to leave. It was the best dentist cleaning service I’ve ever experienced and they even gave me a travel kit of a free toothbrush, toothpaste, and the cutest mini floss. CAN’T THEY ALL BE LIKE THIS?!

Mark W. from Long Beach, CA (Source: Yelp)


I first came to Dr. Cho when my primary doctor (at the time next door) recommended him several years ago.  The office is clean and pleasant.  The office is right off Newport Blvd and easy to get to. They try to make going to the dentist less traumatic for those who fear their semiannual cleanings and check ups.  Hey have TVs and headphones for those patients. The staff is pleasant and always supportive.  Their office is very good about follow ups and reminders. Dr. Cho is very cool and total straight-shooter.  He will take the time to answer your questions.

Michelle Y. from Irvine, CA (Source: Yelp)


Awesome dentist! Dr. Cho and his team are great. The office is clean and I love Dr. Cho’s honestly. It took me a while to find a dentist that will give me an honest diagnosis rather than a diagnosis that will financially benefit the dentist. Jennifer the receptionist is very informative and kind. She bills my insurance the day I finish my treatment which is awesome. Kendra the dental assistant is very gentle and friendly. She makes my visit a lot more comfortable and relaxing. And Rachel the hygienist is one of the best hygienist I’ve ever met! She takes her time cleaning your teeth and is extremely thorough. I’ve been putting off my dental care for the longest time, but since I found Smile Spa, I’ve gotten 5 crowns done and I only have 1 crown and 4 fillings to go. Getting my Invisalign done here as well! My teeth are feeling better than ever and I highly recommend Smile Spa. I’ve referred 5 of my friends/colleagues and they all love it here too.

Olga V. from Costa Mesa, CA (Source: Yelp)


Found this place online very close to my home. So I decided to give it a try. The office is great very nice & clean. Not to mention the staff very nice and understanding. Love, loved this dental office, I will definitely recommend it . Dr was great made me feel calm & his assistant Inga is the best she was so nice to me and  reassured me everything would be ok.

Valeria L. from Lakewood, CA (Source: Yelp)


I have been coming to this office for 4 years now and am very happy with my results. Dr. Cho and his staff are very welcoming. It almost makes me feel at home. I had short teeth that made it embarrassing for me to smile. Dr. Cho did a procedure on me called crown lengthening which made my teeth look larger, now I have a big white smile. Now I feel comfortable smiling in pictures! I definitely recommend this office to go to. This office does everything you need. No need to go to specialist Dr. Cho does it all!

Alex H. from Newport Beach, CA (Source: Yelp)


I have been coming to see Rachel and Dr. Cho for about 3 years now. I always feel like my teeth are in great hands and that they do a great job. The staff is really nice and courteous. The office is modern and inviting and it’s just a good place to get your teeth cleaned. I’ve been coming every 3 months since 2015 and even after moving farther away I refuse to change my dentist!

Julia C. from Costa Mesa, CA (Source: Yelp)


Best dental experience ever.  My search for a qualified and honest dentist stops here!  I had some horrible past experiences that I thought left me scarred for life but then I found Dr. Cho.  I don’t dread going to the dentist anymore and actually like it.  My procedures have been virtually painless.  I have great teeth now and don’t have to drag myself in every time. I actually enjoy going to his office.  His Newport Beach office is very sterile and nicely decorated and has the latest technology and equipment.  It has a very soothing atmosphere and i’m so relaxed I usually don’t want to leave, unlike most dental offices.  The office staff is also great but the bottom line is you just can’t beat the care that Dr. Cho provides.  Btw, there is nothing he can’t do but he’s honest and conservative so he’ll never push anything on you.  I recently had an implant and considering the procedure it was a good experience and looks amazing!!! Thank you, Dr. Cho!!  I hope anyone reading this review helps you decide to try Dr. Cho because you will not be sorry!!

Isabella D. from Newport Beach, CA (Source: Yelp)


I came down with a toothache and smile spa took me right in. Rachel, the hygienist, was amazing and explained everything so thoroughly. She put me right at ease and was so kind and does a great cleaning. Dr. Cho was great and incredibly ethical. I had a great experience and I recommend anyone looking for a dentist or any dentistry work done to come here! You will not be disappointed! Pricing is great too!

Kyle M. from Costa Mesa, CA (Source: Yelp)


“I’m so glad you made me go…” That certainly wasn’t the reaction I was expecting after making my husband a surprise dentist appointment. But true to form, the staff at Smile Spa Dental were outstanding! The office is so clean and modern, and the spa enhancements are a treat when receiving dental work. We have been recommending the practice to our friends and family, and will continue to do so. If you’re looking for a dentist in the Newport or Costa Mesa area, Smile Spa is absolutely your best bet.

Rose M. from Newport Beach, CA (Source: Yelp)


Scheduling is a breeze! They are always there to take your calls and have 2 offices. One in Newport Beach and the other in Los Angeles. Super easy to find and ample parking. One thing I absolutely love about this office is that I’m in and out! Hardly do they ever make you wait past your appointment time and that makes me very happy. Thank you Smile Spa for keeping my teeth happy and healthy!! 😀

Angelia D. from Lakewood, CA (Source: Yelp)


*This is a very thorough review and I recommend reading it especially if you have anxiety going to the dentist. If you don’t have the time I definitely recommend Dr. Cho and Smile Spa they’re fantastic!* To start off with I have a lot of anxiety going to the dentist. When I was a child it was never a pleasant experience for me and the last time I did go, I had two wisdom teeth removed. Being discouraged and embarrassed I have not been in years. However, I do feel compelled to share my entire experience. Maybe it will help someone who feels the way I felt. To start off with, making my appointment was extremely easy and Jennifer was so sweet and helpful. The day before my appointment I received a confirmation call, not by a computer either! I am a big fan of human interaction. The day of my appointment I got called into work and was worried I would be late. I called the office and Jennifer assured me I would be fine and to drive safely. Getting there was very easy and parking was provided for free! A lot of places in Newport require you to either pay for parking or a stamp to redeem your ticket! Anyways, there’s an elevator if you need it however, I need the exercise after the holidays so I took the stairs.   The office was just ahead on the right, very easy to find and good signage. The office is very clean and they offer beverages in the waiting are. The paper work was only one page!!! The rest you can read and sign on a pad that connects to the computer! I love how they have gone green by saving this extra paper work! Way to be considerate of the environment  great job! While waiting I explained to Jennifer about my anxiety and how I was feeling scared. She assured me I would be okay and they would take good care of me. To keep my mind off of things she created a wonderful conversation with me and I found out it was her birthday! It totally took my mind off things while I waited. Jennifer has the best customer service I have ever seen! Rachel was my dental hygienist and was so sweet!! Oh my gosh! I’m so embarrassed  but this is important to me. She walked me through step by step and explained everything that was going on. This really helped me calm down and I really want to fix my teeth so I can show these beauty’s off! We started with X-Rays and to my surprise, I was not put into a tiny room with a giant machine. I got to stay in the same chair my whole appointment! It’s so nice not having to get up and grab all your stuff to go to another room. As usual the X-Rays can be a little uncomfortable with the mouth pieces but Rachel is fast like lightening! After X-Rays it was time to measure my gums. This made me very nervous and the tools looked intimidating but Rachel was there for me. She explained to me exactly what was going to happen and what it may feel like. There were a few points where it felt sensitive but she was very gentle. Rachel even asked me how I was doing and told me there’s just a few more, she even offered to give me a break but I was determined to stick it through.  To speed up the process she asked Inga to come in to help input the numbers into the computer. Inga was so sweet and when she saw my anxiety she gave me hug and even held my hand! There was another patient so she had to go but I couldn’t believe how much I felt cared for by the entire staff! Now it’s cleaning time! Oh my gosh! I’m so scared  I know it’s going to hurt.  I told Rachel I was afraid of the pain and was getting really nervous. She assured me I was going to be okay and offered to numb my gums for the cleaning! Oh thank you lord  she was so thorough too! Did not miss a spot! I still experienced some pain but I could only imagine what it would have felt like if I didn’t have it. I was told it would taste bad but they sucked it out before I could taste it. Before I knew it she was done  and taught me some new techniques with flossing and sent home a special medicated mouth wash for me that was very cost effective too. Now it is time for Dr. Cho to come take a look. He was there in two shakes of a lambs tail! He examined me throughly and was extremely nice and professional.  I’m so embarrassed but I’m happy I came in before it was too late. After my exam I found out exactly just how much work my teeth needed. This made my anxiety almost sky rocket just thinking of being in the chair and the possibility of pain. Yes, I’m a big baby  They offered for me to start the same day because he had some time in his schedule however, my nerves got the best of me and decided it was best to rescheduled. Dr. Cho recognized my anxiety and actually prescribed me some medication for my next visit.  He said it will help me relax but to have someone drive me to and from my appointment of course. Rachel then gave me a hot towel that smelled like lavender and checking out was super easy.  I hope this was helpful

Alison R. from Lake Forest, CA (Source: Yelp)


Came here to Dr. Cho’s office about 4 times now.  Every time I have had a pleasant experience.  The staff is very nice and accommodating.  And Dr. Cho is very nice and good at his job.  I had 4 wisdom teeth removed all at the same time, and Dr. Cho was really fast and good at his job. The procedure was done very quickly and efficiently. Not a bad experience at all. Then I developed dry socket which sucked haha. However Dr. Cho saw me and fixed my problem and I was ok again. The pain literally disappeared right after he fixed me. I also got deep cleaning done and now my teeth are super clean.  My overall experience here was great!  So great that I scheduled an appointment for my boyfriend.  I’m sure his experience will be just as good as mine.

Bri L. from Laguna Beach, CA (Source: Yelp)


I live in Laguna Beach but drove to Newport just to come to my favorite dentist! The service here is first class with a warm smiling welcome to the way they advise you in the chair .. and really the whole energy of this place. I never felt like they were pushing any extra services which is why I left my previous dentist. Smile spa has massage chairs and a hot towel afterwards. Normally the dentist is a painful experience but I felt like I was in a spa! Check out Groupon for special cleaning & xray deals. Highly recommend this dentist!

Josh B. from Thousand Oaks, CA (Source: Yelp)


Best F’in Hygienist I’ve ever been too. I’m a tall order when it comes to dental work. Have not been to a dentist in a couple years to be honest. But Rachel made my stressful dental trip a breeze. I hate the dentist to be honest. Gives me anxiety. But Rachel was incredible and really calmed my nerves. She told me everything she was doing, was very clear, and made the experience actually enjoyable. Yes enjoyable at the dentist. Smile spa made that possible. I will definitely be back! Thank you Rachel and Dr Cho!

Lena F. from Newport Beach, CA (Source: Yelp)


I had the last phase of my implant done by Dr. Cho this past weekend and the end result is amazing!! He’s a great dentist who actually cares about his patients and is very detail oriented and thorough. It’s very hard to trust dentists these days, all they see is $$$! His pricing is very reasonable and his entire staff is very personable and nice. I have no complaints about any of my visits here and would recommend Dr. Cho in a heartbeat.

Catherine C. from Irvine, CA (Source: Yelp)


You walk in Smile Spa Dental and are immediately impressed.  It is clean, modern and inviting.  There is a massage chair to relax in while  you wait.  The staff are friendly, professional and extremely helpful.  I usually dislike going to the dentist.  Smile Spa Dental makes the experience a positive one. While in the chair you can listen to music,  watch a movie or show.  Dr. Cho  and his staff are the best.  If you live in Orange county and looking for a new dentist switch to Smile Spa Dental.

Kortnee D. from Los Angeles, CA (Source: Yelp)


I had a wonderful experience getting my teeth cleaned by Rachel today! She really went above and beyond to clean my teeth after just getting my braces off. I had a lot of cement, and tarter build up and she really got in there and helped remove it all. She seemed to really care about getting my teeth squeaky clean and I appreciate that. I also enjoyed the attention to detail and not trying to up sell me on additional procedures!! A+

P. L. from Irvine, CA (Source: Yelp)


I’ve had to move around a lot from state to state and Dr. Cho is the best I’ve ever had! His staff are incredible as well. They do a good job with scheduling so the move you right in when you arrive. They don’t overbook as well so you are getting the attention you deserve. I have heard that dentist can be like mechanics in that they recommend procedures that are un-necessary. Dr. Cho with give you the pros and cons and only advise on what’s needed. I really do get a feeling that they care for their patients. The facility looks very clean and modern and they also have a massage chair which is a plus. They have gone above and beyond to really make something as stressful as going to the dentist feel like you’re right at home. I highly recommend giving Dr. Cho a visit!

Jamie S. from Irvine, CA (Source: Yelp)


Dr. Arnold Cho has done teeth cleaning and examinations many times as well as an impression for retainers.  I have enjoyed coming to his office every time.  He is such a kind dentist and I felt very comfortable sitting in the chair that normally freaks me out.  The office decor itself is quite chic and clean…and the receptionist is always very sweet as well.  I would definitely recommend him to anyone looking for a great and trustworthy dentist…he can turn your teeth into a fabulous smile!
